CVE-2017-15068
The Intel Puma 5, 6, and 7 chips, as used on various Comcast branded devices, allow remote attackers to cause a denial of service (performance degradation) by sending a moderate volume of small packets to many TCP or UDP ports. NOTE: Intel has advised that they are only a hardware manufacturer in this instance; they do NOT own the mitigation distribution channel for these chips. Any details about mitigations would need to come from Comcast.
